GENERAL DESCRIPTION
The 74LVC157 is a quad 2-input multiplexer designed
for 1.2V to 3.6V operating voltage. The inputs from
3.3V or 5V devices make this device can be used as a
translator in a mixed 3.3V and 5V system environment.
The enable input (E) is active low. When E is held high,
the 1Y to 4Y outputs are forced to low-state no matter
what the conditions of the inputs are. When pin E is
held low, four bits of data are selected from one of two
sources that are determined by the state of the
common data selection input (S), and are routed to the
four outputs. The four outputs present the true
(non-inverting) selected data. The S input can also be
used as function generator
